[quote name=`Kevin Brown`]...It`s why many of us using the smaller Rupes LHR75 3" Air-Powered Mini Random Orbital just cannot believe that the paint surface is not hazed or scoured after we`ve polished using a dinky pad @ 8,000-10,000 RPM. It is a shocker, but what a difference there is between using it compared to a Griot`s 3" machine or a Metabo SXE400.
Belated Q about the above, good thing that older post keeps showing up- Are you saying there is an appreciable performance diff between the Rupes LHR75 3" Air Powered Mini Random Orbital and the GG 3" *pneumatic* RO? I have no doubt there are significant *ergonomic* advantages, but I`m not gonna upgrade over those... :grinno:
"You see my vision of what I was thinking about is during the finishing polish (rather than compounding) when I use 85RD I dont see much dusting therefore I don`t really imagine the particles of clear coat are going anywhere except into the pad until I release them with a brush after my section is complete. The edge gradually capturing them.... Hmmmm I hadn`t considered that but don`t think it accounts for much clear coat capture"
Corey,
I`m going to try to touch on a couple of things here to maybe help you imagine what`s going on. I think you`d agree that 106 cuts more than 85 does and it also dusts more. From what I`ve been told by industry insiders is that both have the same "size & type" of particles in them used to "cut". It`s just that 106 has many more of them. If my memory holds true, this is close to the same with 105 & 205. So while we`re "compounding" and the "liquid" dries up there are more particles left behind. ie dust. Now while you may not see as much dusting with Menzerna`s as you do with Megs that`s because one uses small particles clumped together to get a good initial cut then they break away into smaller pieces to give a finer cut and the other uses equal sized particles that don`t "break up" so there are more there to get the cut quicker. That`s why when using diminishing abrasives you have to fully "work" or "flash" it to get the results intended where with SMAT you just polish until you get the results you are looking for.
As for the edge of the pad not affecting the end result much. Imagine taking your softest and nicest microfiber towel and contaminating the leading edge with anything that would scratch the paint. If you rubbed it across the surface, even though 99% of the towel was clean, it would scour, correct? Now picture the edge of the pad holding debris, not only is it moving faster than wiping by hand, but the leading edge also becomes the trailing edge. So the first and last part of the pad that touches the paint is the part that is loaded with debris.
Hope this helps.
Mike

Remember, George, that the LHR75 is both a 3" machine AND a large-stroke DA at 15mm; the Griot`s 3" pneumatic has I believe either a 5/16" stroke, or a 3/8" stroke. While I don`t (yet) have an LHR75 on hand, I do have a Chicago Pneumatic 3" which is very similar to your Griot`s. If my experiences with bigger scale large-stroke DAs like the Dynabrade and the Rupes LHR21E are any reliable indication, I would say that specification alone would account for significant performance gains with regard to overall capability.
Of course, there are still always going to be situations where a small-stroke tool is better suited to a given task, but I`m sold enough on Rupes that I plan on bringing the entire Bigfoot arsenal into my collection sooner than later.

Another "Mike get`s it" is in order, the NXT get together was review for alot of what I do but when Brent spoke (Megs chemist) I really opened my ears as it eliminated a few questions in my mind and was validation for others(Will not comment due to NDA agreement).
Paint correction with the current and to be released gear is SO MUCH EASIER than back in the day it is almost funny, the Rupes with certain pads and gear is the standard as of now.

Please forgive a few newb questions.
1. Can you use a 5 inch backing plate/pads with this? I have only seen 6in mentioned. I have the PC7424XP right now and didn`t like using 6inch pads. With the longer throw and a 6 in pad, I`m afraid there will be a lot of places I couldn`t use it on and would have to use another polisher which would defeat the purpose.
2. How do the Rupes pads compare to industry standards like LC pads?
i would like to know that also[to lazy to read all the posts]

Rupes also makes the BigFoot LHR 15ES, which is virtually identical to the LHR 21ES.
LHR15 ES:
• 5" backing plate
• 15mm-diameter orbit
• 5,000 RPM/OPM maximum speed
• $349 approximate
LHR21 ES
• 6" backing plate
• 21mm-diameter orbit
• 4,200 RPM/OPM maximum speed
• $394 approximate
Keep in mind that when you drop backing plate diameter, you are essentially shrinking the "platform" size.

As an example, the Meguiar`s G110v2 has an 8mm orbit diameter, excellent low speed performance (top-end isn`t as high as a typical Griot`s, but the latest versions are pretty speedy, and the G110v2 is very reliable nowadays. The backing plate can be easily exchanged, so you could feasibly use any size of plate you`d like. The mid-range stroke size allows you to accomplish polishing in tight areas, yet it can cut very well in the larger areas, especially if you use the proper backing plate.
Oops! Just re-read... you already own a PC. Oh well, no need to erase the stuff about the G110v2.

I have to say that when I run the 3" air-powered machine, the Rupes pads "feel" fantastic, not puffy, and even when they warm up (something kinda new... warm pads!), they continue to perform well, and squeegee the surface clean.
80/100mm (3") pad - $8.95 approximate
80mm Velcro side, flares to 100mm at the polishing face
130/150mm (5") pad - $12.95 approximate
130mm Velcro side, flares to 150mm at the polishing face
155/180mm (6") pad - $14.95 approximate
155mm Velcro side, flares to 180mm at the polishing face
Here are the Rupes 3" pads.

As far as I know there is no other backing plate for the 21mm. Although the 15mm version has a 5" backing plate. Keep in mind these machines were designed specifically for paint correction and to be used day after day and hour after hour. By changing the backing plate it`s quite possible you`d upset the incredible balance that Rupes has engineered into them.
I know we`re used to changing plates on our da`s to suit our needs but they weren`t designed for comfort or with the thought of paint correction in mind. Do I think I can get every nook and cranny with the Bigfoot? I doubt it, but I also couldn`t get them all with my G110V2 either. This is where the microfiber pads really do help because you can edge them. I worked a radius on a hood, that with foam it would have only hit the edges but the microfiber pad was able to follow the contour precisely.
I`m not going to throw away my rotary`s or other da`s but I sure wont be reaching for them all too often.
As for the pads, I didn`t order any so maybe someone else will chime in.

KB,
Thanks for the reply. I`m looking to add another polisher on top of my PC. I had considered something like a FLEX but I started hearing about the Bigfoot. IMO there is no one tool that will do everything. The PC is impressive as I have personally seen what it can do. I`m just wanting something more powerful for those really bad jobs.
Kevin Brown- Your best guess...how would those flared 3" pads work out on the GG 3" pneumatic RO?
C. Charles Hahn- Thanks for the info Re the GG 3" Pneu. vs. Rupes.
Oh man, I`m just sooo trying to not add to the polisher Accumulation I mean, sheesh...I`m always on these polisher-threads and here I hardly ever do any polishing! And anyhow, I think Accumulatorette already has something (in the tool category) for me this Christmas.
I really liked the 3" pads on the LHR75. Haven`t tried the larger ones yet but will give them a whirl soon and would expect them to perform as well as the smaller ones.

I have also heard the same from the "industry insiders" about the menzerna products but never heard that about 105/205. Very interesting! Are you sure it`s the case with 105/205?
As for the towel and pad analogy I would disagree that it`s a fair comparison. What I am saying is the edge of the pad is not more contaminated in the manner theoretically suggested. If it was we would find a different end result which I do not see. Perhaps it is due to a completely different technique, tools, etc. but I don`t see it. Rather it seems all the particles including polish and paint are cut to a size that does not affect the finish and are evenly pressed into the pad pores or dust off away from the surface. As long as it`s made clean after each section there isn`t an issue and the finish can be flawless in the real world regardless of theory.
Thank you,
Corey
Wow, only $400? I had been avoiding threads because i thought they were gonna be 700 or whatever others were estimating. Pff...i think the price separates the hobbyists from the pros. For 400...reserve me one. I will email you asap!
If you don`t know the answer, ask the question. The worst that can happen is that you find out the answer.
